Engineered for growers who demand precision, power, and performance — the Black Flag Potting Mix 50/30/20 is your ultimate all-in-one substrate solution.

Designed in-house at Black Flag Horticulture, this premium growing media blends 50% Coco Coir, 30% Perlite, and 20% Aqua Pebbles — giving you an ultra-versatile substrate with exceptional water retention, drainage, and root aeration.

🌱 What Makes It Stand Out?

  • 🌴 50% Premium Coco Coir: Sustainably sourced and pre-buffered, coco retains moisture beautifully while preventing compaction — perfect for consistent hydration and strong root establishment.

  • 🪨 30% Expanded Perlite: Increases oxygen levels at the root zone and enhances drainage — critical for preventing root rot and promoting explosive plant growth.

  • 💧 20% Aqua Pebbles (Clay Pebbles): Boosts structural stability and maintains airflow deep into your pots. These pebbles reduce compaction and act as natural buffers during feeding cycles.

Whether you’re growing herbs, exotic flowers, or that “indoor tomato plant,” this mix is built for performance in hydroponic, indoor, or traditional container systems.


📏 Available Sizes:

  • 5 Litres – Great for seedlings, clones, or compact pots

  • 10 Litres – Ideal for hobby growers and balcony setups

  • 20 Litres – Perfect for full-cycle plants or serious gardeners


💡 Why Growers Love It:

  • Excellent for hand-watering, drip systems, or automated setups

  • Low EC and buffered for safety – no guesswork, just grow
